CNC Machining
Aluminium 5052-H112 is a lightweight aluminium-magnesium alloy with a natural silver-white appearance. It offers good corrosion resistance, weldability and formability, making it useful for covers, housings, panels and marine components.
The H112 condition describes material that acquires some temper during shaping, with specified mechanical-property limits. Unlike heat-treatable alloys such as 6061, aluminium 5052 cannot be strengthened by precipitation heat treatment; its strength can be increased through cold working.
Custom parts can be produced using CNC milling or turning, although its softer cutting behaviour requires suitable tooling and machining conditions. As-machined surfaces retain fine tooling marks, while anodising can be specified where available for surface protection and appearance.

Values shown are typical supplier figures for Aluminium 5052-H112 and may vary with stock condition. Please confirm critical properties before production.
5052 can be machined well, but it is softer and less free-cutting than 6061, so it can produce longer chips and burrs. It is chosen more for corrosion resistance and formability than for machinability.
As a softer, non-heat-treatable alloy, thin walls and fine threads need more care than on 6061. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.
Yes. 5052 anodises well and has outstanding weldability, which makes it a strong choice for welded marine and pressure parts.
Typical uses include marine and shipbuilding parts, pressure vessel components, transport and vehicle parts, and architectural and decorative trim.
Choose 5052 for excellent corrosion resistance, especially in salt-water environments, and for welded or formed parts. Choose 6061 when you need higher strength and easier machining. 5052 cannot be strengthened by heat treatment.
The typical lead time shown for aluminium 5052 is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
